Abstract
A foreign matter discharge hole 83 is formed in the lowest position of the cover 70 in the attached state and the size of the foreign matter discharge hole 83 is equal to the size of the gap between the air outlet 75 and the harness 36 Or more. Accordingly, the foreign matter contained in the cover 70 can be surely discharged through the foreign matter discharge hole 83 out of the cover 70. [0054]
Description
The present invention relates to a shock absorber having a damping force adjusting mechanism.
In the damping force adjusting type shock absorber, there is known a constitution in which a harness connected to the damping force adjusting mechanism is covered with a cover in which the outlet of the harness is formed. In such a damping force adjusting type shock absorber, there is a fear that the foreign matter entering the cover through the gap between the harness and the outlet of the harness, clogs the drain hole of the cover.
An example of such a structure is disclosed in Japanese Utility Model Publication No. 62-60736.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a shock absorber capable of surely discharging a foreign matter contained in a cover through a gap between a harness and a harness.
A shock absorber according to the present invention is a damping force adjusting type shock absorber attached between two relatively movable members. The shock absorber includes a cylinder in which a working fluid is sealed, a piston inserted in the cylinder, and a piston rod connected to the piston, And a cover covering at least a part of the outer periphery of the housing. The damping force adjusting mechanism includes a solenoid, a harness for supplying power to the solenoid from the outside, a damping force adjusting mechanism installed in the housing protruding to the side of the cylinder, Wherein a foreign matter discharge hole is formed in the cover to take out the harness and in a position to be a lower side in the attached state, and the size of the foreign matter discharge hole is equal to or larger than the size of the gap between the air outlet and the harness Or greater.
According to the present invention, it is possible to reliably discharge the foreign matter contained in the cover through the gap between the harness and the outlet of the harness.
Fig. 1 is a cross-sectional view taken along the axial plane of the shock absorber according to the present embodiment, and particularly shows a damping force adjusting mechanism in a virtual line.
Fig. 2 is an AA sectional view in Fig. 1, particularly showing the outer tube, housing, cover and mounting bracket;
Fig. 3 is an explanatory view of the present embodiment and is an exploded perspective view of an outer tube to which a cover and a mounting bracket are joined.
4 is an enlarged view of a main portion of the shock absorber according to the embodiment.
Fig. 5 is an explanatory view of this embodiment showing a state in which the cover is closest to the upper surface of the curb in the attached state.
